Built to Series I4S specifications, it features a 3\/4-inch cutting diameter, 4-inch length of cut, and a 7-inch overall length with a straight-cylindrical 3\/4-inch shank. The 4-flute, right-hand helical geometry runs at a 30-degree helix angle, promoting efficient chip evacuation and smooth surface finishes. A TiAlN coating adds thermal resistance and wear protection, extending tool life in demanding cutting environments. This end mill is centercutting capable, making it suitable for plunge entry as well as conventional milling passes.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for machining steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. It performs in both roughing and finishing operations on CNC machining centers and manual knee mills where a regular-length, straight-shank tool is appropriate. The right-hand cutting direction and helical flute design make it a practical choice for general-purpose production milling in job shops and manufacturing facilities. No chipbreaker or variable helix features are present, keeping the geometry straightforward for consistent, predictable performance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous and non-ferrous applications\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating provides elevated-temperature hardness and extended tool life\u003c\/li\u003e\n  \u003cli\u003e4-flute, 30-degree right-hand helix geometry for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry into workpiece material\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank for secure, concentric clamping in standard collets or end mill holders\u003c\/li\u003e\n  \u003cli\u003eSeries I4S regular-length profile balances reach and stiffness for a wide range of milling tasks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with CNC machining centers and manual milling machines equipped with standard 3\/4-inch collets or end mill holders.

Power down and lock out the spindle before loading or unloading the tool. Seat the shank fully into the holder and torque the collet or set screws according to the toolholder manufacturer specifications. Inspect the cutting edges and coating for damage before each use; do not run a chipped or delaminated end mill.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inches (0.75 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 4.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: I4S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Superalloys and Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.242 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WIDIA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5879189\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WIDIA","offers":[{"title":"Default Title","offer_id":67917648658738,"sku":"5879189","price":478.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/559aeb55d436c4ba723853148c2e375a_419602f2-6fb9-4f1a-bd2e-dea1c46f2340.jpg?v=1791264443","url":"https:\/\/voomisupply.com\/products\/widia-5879189-square-end-mill-3-4-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
